Incog,
That is exciting. If you are inclined to get the achievment test, then I'm going to suggest that you sign up for the Explore as well, if it's offered near you. Why?
1) Insurance
2) Help you fill out the Iowa Acceleration Scale Manual (although I've forgotten where you stand on grade skips. Even if you aren't interested, I found it really helpful to clear my mind about who my kid is.)
3) Many kids enjoy taking these kind of test.
Anyway, I think you got a good letter, although not as good as one might have wished.
Smiles,
Trinity
